Motivation to cum? :-/

Whenever me and my boyfriend hangout (which is frequently) I can give him a hj ect and get him to climax easy, but whenever it comes to be my turn, the idea just kind of turns me off. It takes so much effort to cum by someone else's doing, am I the only one? I'm feeling completely vulnerable and alone atm.. Do I make him keep trying until I manage to climax or should I keep faking it to make things easier <
